NAME

       DPLINE - Draws a straight-line segment between two points in the user coordinate system.

SYNOPSIS

       CALL DPLINE (XCP1,YCP1,XCP2,YCP2)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_dpline (float xcp1, float ycp1, float xcp2, float ycp2);

DESCRIPTION

       XCP1        (an input expression of type REAL) specifies the X coordinate of a point at
                   the beginning of the straight-line segment.

       YCP1        (an input expression of type REAL) specifies the Y coordinate of a point at
                   the beginning of the straight-line segment.

       XCP2        (an input expression of type REAL) specifies the X coordinate of a point at
                   the end of the straight-line segment.

       YCP2        (an input expression of type REAL) specifies the Y coordinate of a point at
                   the end of the straight-line segment.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       DPLINE maps the input coordinates to the fractional system and then passes them on to
       DPDRAW.  Even is smoothing is turned on, no smoothing is done by a call to DPLINE.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tdshpk.

ACCESS

       To use DPLINE or c_dpline, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
